Abstract

Disclosed is a lighting device using a light emitting element wafer array, the lighting device comprising: a substrate; a plurality of light emitting element wafer arrays attached to the substrate and arranged in a matrix shape, the light emitting element wafer including a light emitting surface and an electrode forming surface facing the light emitting surface, the flip chip bonding electrode being formed on the electrode forming surface; and a transparent support layer covering light-emitting surfaces of the plurality of light-emitting element wafers and fixing the plurality of light-emitting element wafers at a constant light source interval, the transparent support layer including a fluorescent material that absorbs light emitted through the light-emitting surfaces to change a wavelength of the light.

Description

technical field [0001] The present invention relates to a lighting device using a light-emitting element chip array and a method thereof, and more particularly, to a lighting device using a light-emitting element chip array and a method thereof, wherein, by directly using a wafer-level light-emitting element (LED) Wafers are not required to be sorted into good / bad to manufacture the light source module, thereby reducing the manufacturing cost. Background technique [0002] For example, light-emitting elements such as light-emitting diodes (LEDs) are one of semiconductor elements that convert electrical energy into light, and are attracting attention as next-generation light sources that replace conventional fluorescent lamps and incandescent lamps. [0003] Since light-emitting diodes generate light using a potential difference of semiconductor elements, light-emitting diodes have environmentally friendly characteristics such as longer lifespan, fast response speed, and low ...
